Things to Consider Before Buying A 6X8 Car Speaker
A number of factors determine whether a car speaker is the best choice for the car and whether it meets the buyer’s preferences. You need to consider these factors when shopping for the best 6x8 car speaker. Of course, the first step is deciding whether to go for component speakers or full-range speakers.
Component Versus Full-Range Speakers
None of these two speaker types can be said to be better than the other. Component speakers are known to provide better sound, though they are more expensive than full-range speakers. So if you consider sound quality very important in your search for the best 6x8 car speaker, then these are the better option for you.
Full-range/coaxial speakers are cheaper, easier to install and will do the job well. Therefore, if you’ve prioritized ease of installation and lower price, then you should look for the best full-range speaker. A number of them have been featured in our list of top 10 6x8 car speakers.
After you decide to go for component or coaxial speakers, compare the available speakers of your preferred type before coming up with the final decision.
Below are the most important factors to check in a car speaker that you are considering for purchase:
1. The sensitivity of the speaker: How much a speaker yields from the aplied power is its sensitivity. The level of sensitivity to choose depends on the how the existing car stereo is powered. Most factory-installed car stereos are low-powered (about 15 watts RMS perchannel and lower) and they require speakers with sensitivity levels above 90dB. For high-powered systems (16 watts RMS or greater)consider speakers with lower sensitivity levels.
2. Power-handling capabilities: The RMS and peak power metrics of a speaker informs you about how much power the speaker can handle. Alow-powered system doesn’t need speakers made to handle high power levels. On the other hand, if your system has powerful external amps, then you need speakers that can handle almost the same power as the output of the amps. You should keenly check the maximum RMS power-handling and not the peak power-handling.
3. Build quality: To ensure that the durability and sound quality of the speaker you chose is satisfactory, look for a speaker whose woofer, tweeter and surround material are durable.
- A stiff, lightweight, and water-resistant material is required for the woofer to effectively produce low notes in your music. Synthetic films like polypropylene and woven fabrics coated with metals such as titanium or aluminum are the best candidates for great woofer material.
- The material used to make the tweeter(s) in an audio system greatly affects the quality of sound the system produces. In general, soft materials like textile blends, poly, or silk make for the best tweeter material for the production of a refined sound. Harder materials like ceramics, graphite, and metal are also used by those who like highs bright and snappy.
- The surround of a woofer allows the cone to move freely and produce a bold bass. To perform this vital role, the speaker surround should be made of material that can withstand temperature and humidity variations. Cloth and foam are good low-cost surround materials but the best performer is rubber.
4. Car size and configuration: It’s important that you know the specifications of the speakers you need so as to get the best 6x8 car speaker that fits into your car. You can check the factory speakers to know their sizes and configurations if you have experience in car audio systems.
If you are sure you’ll replace the existing speakers soon, you can remove them and take their measurements. You can also get the speaker’s specifications from stores that sell car speakers.

Since we considered all these factors when selecting the best 6x8 car speaker from every brand, it is highly likely that you’ll find the perfect one for your vehicle.
